A general approach for robust integrated polarization rotators
Alonso-Ramos, C.; Halir, Robert; Ortega-Moñux, Alejandro; Cheben, Pavel; Vivien, Laurent; [et al.] (International Society for Optics and Photonics, 2013)Integrated polarization rotators suffer from very high sensitivity to fabrication errors. A polarization rotator scheme that substantially increases fabrication tolerances is proposed. In the proposed scheme, two tunable ... -
Re-inventing Multimode Interference Couplers Using Subwavelength Gratings
Ortega-Moñux, Alejandro; Halir, Robert; Maese Novo, Alejandro; Alonso-Ramos, C.; Zavargo-Peche, Luis; [et al.] (European Physical Society, IEEE, The Optical Society, 2013)We use the concept of subwavelength grating (SWG) refractive-index-engineering to propose and experimentally demonstrate a reduced size, slotted 2x2 MMI coupler. We also present an ultra-broadband 2x2 MMI coupler which ... -
Robust and tunable integrated polarization rotator
Alonso-Ramos, C.; Halir, Robert; Ortega-Moñux, Alejandro; Cheben, Pavel; Vivien, Laurent; [et al.] (2014-03-11)Integrated polarization rotators suffer from very high sensitivity to fabrication errors. A polarization rotator scheme that substantially increases fabrication tolerances is proposed. In the proposed scheme, two tunable ... -
Silicon-on-insulator polarization controller with relaxed fabrication tolerances
Sarmiento-Merenguel, J.D; Alonso-Ramos, C.; Halir, Robert; Vivien, L.; Cheben, Pavel; [et al.] (2014-07-31)Polarization control is essential in applications ranging from optical communications to interferometric sensors. The implementation of in- tegrated polarization controllers is challenging as they require polariza- tion ... -
Subwavelength metamaterial structures for silicon photonics
Wanguemert-Perez, Juan Gonzalo; Sanchez-Postigo, Alejandro; Luque-González, Jose Manuel; Sarmiento-Merenguel, Jose Darío; Halir, Robert; [et al.] (Photonics North, 2017)Sub-wavelength periodic metamaterial structures are enabling the design of silicon photonic devices with unprecedented performance in the near infrared band. However, for applications in the promising mid-infrared band it ...
